| 摘 要： | 研究卫星对移动目标的动态跟踪问题，主要解决卫星的实时指向计算。本文在已知移动目标的位置信息情况下，建立卫星观测目标的空间几何模型；利用STK（Satellite Tool Kit）软件辅助构建卫星对移动目标的指向序列，设计跟踪曲线的分段拟合方法；建立在时统误差影响下卫星视轴切换的约束模型。通过实验验证了分段曲线拟合方法对于减小误差的有效性，可以较好地提高卫星对移动目标跟踪的准确性和时效性。

| Abstract: | This paper studies on satellite dynamic tracing problem of moving targets, where the main point is the real-time pointing calculation. Based on the location information of moving targets, a space geometric model of satellite observing target is built. Pointing sequence of satellite to moving targets is generated with the help of STK (Satellite Tool Kit), followed with a piecewise fitting method design for tracing curve. Finally a constraint model of satellite optical axis switching under the influence of system time error is built. Experiment results show the validity of piecewise fitting method in error decreasing, which helps to improve the satellite tracing precision of moving targets. |
